Capsaicinoids, the active compounds in chili peppers, have a long tradition of use as decongestants for colds, especially in folk medicine. The warming, pungent sensation caused by capsaicin can temporarily clear nasal passages by stimulating nerve endings and promoting mucus secretion, leading to a perceived relief from nasal congestion. This practice is rooted in traditional medicine and home remedies, where spicy foods or topical preparations containing capsaicin are used to "open up" the sinuses.

Scientifically, there is limited but suggestive evidence that capsaicinoids can provide symptomatic relief for nasal congestion. Some small clinical studies and trials using intranasal capsaicin sprays have found short-term improvements in symptoms of non-allergic rhinitis, but the evidence is not robust or specific to the common cold. The mechanism is thought to involve desensitization of sensory neurons and increased nasal secretion. However, capsaicin use can also cause significant irritation, burning sensation, and discomfort, making it impractical for widespread use as a cold remedy.

In summary, the use of capsaicinoids for colds as a decongestant is primarily based on traditional practices and anecdotal experience, with only weak scientific evidence supporting their effectiveness. While some people may experience temporary relief, more research is needed to confirm their efficacy and safety for this purpose.
